               In order to carry out the provisions of this article, there are hereby created and
               established certain zones which include all of the land lying within the instrument
               approach zones, noninstrument approach zones, transition zones, horizontal zones and
               conical zones. Such areas and zones are shown on the current county airport height
               restriction ordinance map, which is incorporated by reference and made a part hereof.
               The various zones are established and defined as follows:

               <p class="content2">
                  <span class="ital">Primary surface zone.</span> A rectangular surface longitudinally centered on a runway. The elevation of any point
                  on the primary surface is the same as the elevation of the nearest point on the runway
                  centerline. Runway 11-29: 500 feet wide and extends 200 feet beyond each runway end.

                  longitudinally extending outward and upward from the end of the primary surface. The
                  perimeter of the approach surface coincides with the perimeter of the approach zone,
                  extending per a boundary and slope defined in the following table, and as shown on
                  the county airport height restriction ordinance map.
